China Can Blast Almost Every U.S. Warship Docked in Japan With Ballistic Missiles
Modeled estimates of a Chinese missile blitz are sobering
WIB airWIB sea July 30, 2017 Zachary Keck
While U.S. defense strategists have been focused on China’s so-called “carrier-killer” ballistic missile, as well as Beijing’s aircraft carriers, a new report suggests China’s greatest threat to the United States may be something less eye-catching.
“The greatest military threat to U.S. vital interests in Asia may be one that has received somewhat less attention: the growing capability of China’s missile forces to threaten U.S. bases in the region,” write Thomas Shugart and Javier Gonzalez in a report released last month by the Center for a New American Security.
Gonzalez and Shugart are both commanders in the Navy, and the latter currently serves as a military fellow at CNAS. In the report, they argue that China could use its missile forces to conduct a surprise preemptive strike against U.S. military bases in the region to prevent U.S. intervention in a conflict over Taiwan or the Senkaku Islands.
“Driven partly by distinct first-mover advantages associated with the employment of modern long range precision weaponry, such a preemptive strike appears consistent with available information about China’s missile force doctrine and military strategy,” they write.
Chinese leaders began building up these capabilities after being shocked by America’s overwhelming victory over Saddam Hussein’s forces in the First Gulf War. This led Beijing to transform its Second Artillery Corps from a primarily nuclear force into one consisting of nuclear and precision conventional missiles — both ballistic and cruise. This strategy sought to capitalize on China’s asymmetric advantages such as geography and the low cost of producing missiles.
To achieve a preemptive strike against America’s military bases, China has procured a massive missile force. In fact, Beijing has the largest land-based missile arsenal in the world.
According to Pentagon estimates, this includes 1,200 conventionally armed short-range ballistic missiles, 200 to 300 conventional medium-range ballistic missiles and an unknown number of conventional intermediate-range ballistic missiles, as well as 200 to 300 ground-launched cruise missiles.

Many of these are extremely accurate, which would allow them to destroy targets even without nuclear warheads. As a Rand Corporation report noted, Chinese missiles’ “circular error probabilities have decreased from hundreds of meters in the 1990s to as few as five or ten meters today.”
Some of them, including the much discussed DF-21D “carrier killer” missile, have maneuverable reentry vehicles that further improve accuracy and allows them to evade missile defense systems.
Shugart and Gonzalez also point out that the People’s Liberation Army has carried out drills simulating preemptive attacks against America’s regional military assets. In one such instance, the PLA Rocket Forces “appears to have been practicing on several ship targets of a similar size to U.S. Arleigh Burke-class destroyers moored in a mock port that is a near-mirror image of the actual inner harbor at the U.S. naval base in Yokosuka.”
This is illuminating, the authors note, because the only way the Chinese military could catch three U.S. ships in port is if they conducted a complete surprise attack.
After reviewing Chinese capabilities and doctrines, the authors try to simulate such an attack to judge its effectiveness. Interestingly, while they believe China would strike U.S. bases in Japan and even some Japanese forces, they assume Beijing would avoid attacks on Korea “in order to prevent a distracting second front on the Korean Peninsula while pursuing its primary military goals elsewhere.”
In their simulation, they also assume that Beijing would not initially target America’s base at Guam since it is U.S. territory and China would want to prevent an escalation that could result in America bombing mainland China.
Shugart and Gonzales run two different models of a simulated preemptive attack, keeping in mind what they know about U.S. and allied missile defense systems in the region. In both models, “enough ballistic missiles seemed likely to leak through to cause highly significant damage to U.S. bases and forces in the region.”
Some of the results of the attacks include:
• “Almost every major fixed headquarters and logistical facility struck, with key headquarters struck within the first few minutes of the conflict.”
• “Almost every U.S. ship in port in Japan struck pierside by ballistic missiles.”
• “In most cases, cratering by ballistic missiles of every runway and runway-length taxiway at all major U.S. air bases in Japan.”
• “As a result of runway cratering, headquarters destruction, and air defense degradation, more than 200 trapped U.S. aircraft destroyed on the ground in the first hours of the conflict.”

One silver lining, according to the authors, is that a more robust missile-defense system in Japan — including the deployment of Terminal High Altitude Air Defense and Aegis ballistic-missile-defense destroyers dedicated to protecting U.S. bases in Japan — could reduce the damage of such a surprise attack. While a significant number of missiles would still penetrate defenses in Okinawa, the damage there would be reduced.
More importantly, other U.S. bases in Japan that are situated further away from China could intercept enough missiles to allow planes to get off the ground and ships out of port. The authors also advocate that U.S. regional forces practice rapid evacuation of bases on a regular basis.
This points to another important possibility. While the authors acknowledge that many Sinologists dispute China would conduct a complete surprise attack on U.S. forces, the authors point out that the United States has been surprised before — such as during Pearl Harbor. They also note that this would be consistent with China’s active-defense doctrine. Both of these points are true.
At the same time, Pearl Harbor took place at a time of tremendous tensions between the United States and Japan, and Beijing’s active-defense doctrine has also been executed during similar tense times. If Beijing were to launch preemptive attacks to support an invasion of Taiwan or the Senkaku Islands, it seems likely that there would be high tensions and some indication of troop mobilization on China’s part ahead of time.
If so, there seems to be a simpler way to prevent a nightmare scenario like the one Shugart and Gonzales highlight in the report—namely, to operate with an abundance of caution in dispersing U.S. forces during periods of high tensions. This could be done by taking advantage of the rudimentary World War II air bases America is reportedly reopening in the Pacific, as well as making sure most U.S. ships are out at sea.
Either way, Shugart and Gonzales’s report does a great service in reminding defense analysts that the most exotic threats, like carrier-killer missiles, aren’t necessarily the greatest or likeliest ones. After all, America has more combat power located on its stationary bases in Asia than on an aircraft carrier. And these stationary targets are far easier to destroy.

Tässä tarkempaa selvitystä USS Gerald R. Fordin historiallisesta uusien laitteiden käyttöönotosta. ( AAG ja EMALS )
USS Gerald R. Ford Completes First Arrested Landing and Launch
Story Number: NNS170729-01Release Date: 7/29/2017 9:00:00 AM
A A A
From Commander, Naval Air Forces Atlantic Public Affairs
NORFOLK, Va. (NNS) -- Less than one week after Pres. Donald J. Trump commissioned the U.S. Navy's newest aircraft carrier, USS Gerald R. Ford (CVN 78) launched and recovered its first fixed-wing aircraft July 28, 2017, off the coast of Virginia. The first arrested landing, or "trap", occurred at 3:10 PM (EST) and the first catapult launch happened at 4:37 PM (EST).
Lt. Cmdr. Jamie Struck of Tallmedge, Ohio piloted the F/A-18F Superhornet from Air Test and Evaluation Squadron (VX) 23 based at Patuxent River, Maryland.
The Superhornet caught the number two arresting wire of Ford's advanced arresting gear (AAG) system and was launched from catapult one using the electromagnetic launch system (EMALS).
"Today, USS Gerald R. Ford made history with the successful landing and launching of aircraft from VX-23 using the AAG and EMALS," said Adm. Phil Davidson, commander, U.S. Fleet Forces. "Great work by the Ford team and all the engineers who have worked hard to get the ship ready for this milestone."
"AAG and EMALS have been successfully tested ashore at Lakehurst, New Jersey, but this is the first shipboard recovery and launch of a fleet fixed wing aircraft," said Capt. Rick McCormack, Ford's commanding officer.
"My team has worked closely with industry, Naval Air Systems Command (NAVAIR), and the flight test community to make this historic event in Naval aviation happen. I am very proud of my crew."
The software-controlled AAG is a modular, integrated system that consists of energy absorbers, power conditioning equipment and digital controls, with architecture that provides built-in test and diagnostics, resulting in lower maintenance and manpower requirements. AAG is designed to provide higher reliability and safety margins, as well as to allow for the arrestment of a greater range of aircraft and reduce the fatigue impact load to the aircraft.
The mission and function of EMALS remains the same as the traditional steam catapult; however, it employs entirely different technologies. It delivers necessary higher-launch energy capacity, improvements in system maintenance, increased reliability and efficiency, and more accurate end-speed control and smooth acceleration. EMALS is designed to expand the operational capability of the Navy's future carriers to include all current and future planned carrier aircraft - from lightweight unmanned aircraft to heavy strike fighters.
"I could not be more proud of the men and women who, for the better part of the last two decades, have worked to bring these new technologies to the fleet," said Capt. Stephen Tedford, program manager. "Their perseverance and dedication to service have made this day possible."
"My team has worked very hard, together with experts from NAVAIR, Huntington Ingalls Industries, and General Atomics, to test this first-in-class technology," said Cmdr. Thomas Plott, head of Ford's air department. "Today is a validation of their dedication and hard work."

Useita päällystöön kuuluvaa vapautettu tehtävistään USS Fitzgeraldin törmäyksen takia.
7th Fleet Announces USS Fitzgerald Accountability Determinations
Story Number: NNS170817-25Release Date: 8/17/2017 11:34:00 PM
By U.S. 7th Fleet Public Affairs
YOKOSUKA, Japan (NNS) -- The commanding officer, executive officer and command master chief of the guided-missile destroyer USS Fitzgerald (DDG 62) were relieved of their duties by Vice Adm. Joseph Aucoin, Commander, 7th Fleet Aug, 18.
Additionally, a number of officer and enlisted watch standers were held accountable.
The determinations were made following a thorough review of the facts and circumstances leading up to the June 17 collision between Fitzgerald and the merchant vessel ACX Crystal.
The collision was avoidable and both ships demonstrated poor seamanship. Within Fitzgerald, flawed watch stander teamwork and inadequate leadership contributed to the collision that claimed the lives of seven Fitzgerald Sailors, injured three more and damaged both ships.
With absolute accountability for the safe navigation of Fitzgerald, Cmdr. Bryce Benson was relieved due to a loss of confidence in his ability to lead. He had previously been temporarily relieved of his duties due to medical reasons from injuries sustained during the collision. Benson is being reassigned to Naval District Washington at the Washington Navy Yard, where he will have access to medical facilities in the area.
Inadequate leadership by the executive officer, Cmdr. Sean Babbitt, and command master chief, Master Chief Petty Officer Brice Baldwin, contributed to the lack of watch stander preparedness and readiness that was evident in the events leading up to the collision.
Several junior officers were relieved of their duties due to poor seamanship and flawed teamwork as bridge and combat information center watch standers. Additional administrative actions were taken against members of both watch teams.
Cmdr. Garret Miller will assume command from Fitzgerald's acting commanding officer, Cmdr. John "Jack" Fay sometime mid-to-late-August.
It was also evident from this review that the entire Fitzgerald crew demonstrated real toughness that night. Following the collision these Sailors responded with urgency, determination and creativity to save their ship. Their rigorous damage control efforts and dauntless fighting in the immediate wake of the accident prevented further loss of life.

Kerrotko lisää, miten Obama on vuosituhannen vaihteessa päästänyt Fitzgeraldin kolmikon laivastoon?
Tämä lienee enempi foliohattu-osastoa, mutta tuolla twitterin puolella moni on epäillyt, että onko venäläisten harjoittamalla gps-häirinnällä osuutta asiaan.
Oma mielipiteeni on, että vaikka olisikin, niin kyllä päällystöllä pitäisi siitä huolimatta olla merimiestaitoa sen verran, että osaavat toimia perinteisten menetelmien avulla.

Mistä sitten lieneekään lähtöisin, mutta kyllähän nämä jenkkien törmäilyt näyttävät liittyvän heikkoon merimiestaitoon. Ainakin laivan (laivojen) päällystössä. Onko syynä sitten minkä hallinnon toimet ja mihin kaikkeen se ulottuu tai on ulottumatta on vaikeampi asia sanoa.
